Yo guys. I was Reading a "Predictions for the Final Arc", Where Kubo say a lot of things he want/wanted to do in this Arc (Zaraki's Bankai, Return of Aizen and Shit...). What caught my atention was that Tite said there that Rangiku's Past will be the Key to the History. What do this mean ? I don't think it have anything to do with Misato and Isshin's thing... Maybe something with Gin ? or Aizen ? leave your opinion.
